our minds naturally seek order and patterns to find answers.
our minds automatically switch to a pretend mode to make it seem we know something when we don't.
our minds never forget anything.
our minds demand completion.

How are series and parallel circuits simililar? both have multiple paths for electrons to travel. both require resistors in their circuits. both require a switch to complete the circuit. both have at least one path for electrons to travel.

You have a resistor and a capacitor of unknown values. first, you charge the capacitor and discharge it through the resistor. by monitoring the capacitor voltage on an oscilloscope, you see that the voltage decays to half its initial value in 2.70 miss . you then use the resistor and capacitor to make a low-pass filter. what is the crossover frequency fc?

Select the three ways that the parallel-plate capacitor differs from a car battery.
